SPECIFICATION forming part of Letters Patent N 0. 730,294, dated June 9, 1903. Application filed March 5,1900. Serial No. 7,287. (No model.)-

To all whom, it may concern:

Be it known that I, FREDERICK POLLARD, a subject of the Queen of Great Britain, residing at Cleveland, county of Cuyahoga, and 5 State of Ohio, have invented certain new and useful Improvements in Show-Cases, of which the following is a specification.

- My invention relates to improvements in show-cases, especially to all-glass showcases which are constructed by joining the plates of glass directly together at the front and ends, thereby dispensing with a frame,

except at the back and bottom of the case.

In the accompanying drawings, Figure I is a perspective view of a show-case embodying Fig. III is a cross-section of the upper part of. a show-case provided with my improvements. Fig. IV represents a rear elevation of a portion of my improved top rail.

The frame A consists of a base ct and posts The plates of glass D are secured directly to each other at the front and ends by means of brackets E and are fastened to the base in any suitable and well-known manner. A

0 strip of wood or metal (1 is rigidly secured to the top plate by means of cement f and rivets or screws f and is provided with a downwardly-projecting tongue d, preferably integral therewith. The rail 0. is permanently secured to the posts I) and'is provided with a groove h, adapted to receive and seat the tongue formed on the strip that is secured to the top plate. Instead of a tongue and groove various equivalent forms of construc- 40 tion may be used to interlock the strip and rail, if so desired.

The parts are assembled by building up the sides and ends of the show-case, securing the top plate in position by inserting the tongue on the strip into the groove formed in the rail, and then rigidly securing same together by means of brackets and the screws 1'. A piece of molding j may be placed on the inside of the case to hide the joint between the strip and the rail, and thereby add to the finish and appearance of the case.

In order that the case willstand wear without breaking, it is necessary to have a rigid joint between the top plate'and rail, and the seat of the plate upon the rail or strip to which it is secured must be perfectly smooth, so there will be no stress or strain in the glass. It the seating for the plate is not perfectly smooth or if the plate is secured to the strip tighter at one place than'at another by means of the screws, a strain is produced in the glass that inevitably causes it to break sooner or later. On the other hand, if the glass is not rigidly secured to theframe and any motion whatever is permitted the entire case soon becomes loose, which finally causes its destruction. Heretofore when all-glass show-cases have been shipped with the glass detached great difiiculty has been experienced in getting same properly assembled. Their-sale therefore has either been restricted to the larger communities where skilled workmen could be found or it has been necessary to ship the cases in their finished condition, thereby adding greatly to their cost.

By means of my improvements the case can be assembled by an unskilled workman, as all danger of breaking the glass by uneven strains or by reason of looseness is avoided, thus permitting the case to be shipped wherever' desired with the glass plates detached.

I claim as my invention 1 l. In a show-case, the combination with the frame, of a strip permanently secured to one of the plates of the show-case and engaging with the frame and means to form a rigid joint between said plateand frame, substantially as described.

2. In a show-case, the combination with a rail forming part of the frame, of a strip permanently secured to one of the plates of the show-case and engaging with said frame and means to form a rigid joint between the plate and frame, substantially as described.

3. In a show-case having a glasstop plate, the combination with a rail forming part of the case and provided with a groove in its upper face, of a strip permanently secured to the under side of the plate and provided with a tongue engaging in the groove to form a rigid joint between said plate and rail, and means for permanently securing the tongue in said groove, substantially as described.

In testimony whereof I sign this application, in the presence of two Witnesses, this 15th day of February, 1900.

FREDERICK POLLARD.
